This study examines how the spatial variation of violent conflicts across Nigeria affects household food security, with emphasis on displacement, fatalities, and competition over productive resources. The objective is to capture the regional dynamics of conflict-induced shocks and their implications for food access and dietary diversity. Using nationally representative household survey data and applying two-stage least squares (2SLS) regression to address endogeneity, the analysis evaluates how conflict-related shocks—such as forced migration, abduction, and fatalities—influence food consumption outcomes. The results reveal distinct geographic patterns: Boko Haram insurgency in the North-East, herder–farmer clashes in the North-Central, and communal tensions in the South-South all generate significant declines in household food access, agricultural output, and dietary quality. Women are disproportionately affected, facing heightened nutritional and social vulnerabilities. Conflict-exposed communities suffer deeper livelihood disruptions and demonstrate limited capacity to recover without targeted interventions. The study concludes that violent conflict undermines food security both directly—through displacement and loss of assets—and indirectly, by discouraging agricultural investment and weakening resilience. It recommends contextspecific peacebuilding, stronger land tenure systems to mitigate resource-based disputes, and resilience-building policies targeted at displaced and female-headed households. These findings imply that addressing Nigeria’s food security crisis requires integrating conflict resolution into agricultural and social protection strategies. Without such measures, persistent insecurity will continue to erode household welfare and constrain long-term food system stability
